the idea that scully would take mulder’s name is so ridiculous because how fuckin obvious is it that mulder’s been doodling hearts and “mr fox scully” in his notepad since the moment they met

"It’s like the one friend, I guess, that he has in the world. I mean, I heard a phrase once, somebody was talking about their wife. This was a person who was very inept socially, not the wife, but the man. There were many things said about him that weren’t kind and he said, ‘My wife, who is lovely and social and everything like that, is my human credential.’And like makes him a human being, because people think, ‘well, if she can stand him, he must have some humanity within him’. And sometimes I think about Scully as Mulder’s human credential. It’s the only thing that makes him not crazy in many ways.”
